Sleeper Striped Goby (often sold as the Sand-Sifting/Sleeper Goby, Amblygobius sp.) is a fantastic utility fish for reef and marine aquariums, best known for its constant sand-sifting behaviour and calm, bottom-dwelling personality. With its clean striped pattern and busy “working” nature, it adds both visual interest and practical benefit—helping keep the sandbed turned over and free of detritus pockets.
This goby does best in a mature aquarium with a well-established sandbed, where it can naturally forage throughout the day. Provide a fine-to-medium grain substrate deep enough for sifting and burrowing behaviour, plus stable rockwork placed securely on the tank base (not on shifting sand) to prevent collapses as it digs. They appreciate plenty of hiding spots and will often create a favourite sleeping burrow or sheltered nook under rock ledges.
Feeding is the key to long-term success. While Sleeper Gobies constantly sift sand for microfauna and leftover organics, many systems don’t provide enough natural food to sustain them alone. Offer supplemental feedings of finely chopped meaty foods (mysis, enriched brine, copepods, small pellets) once or twice daily—especially in newer tanks or very “clean” systems. A well-fed goby maintains good body weight and sifts more consistently without slowly losing condition.
Temperament is generally peaceful, making them a great fit for community reef tanks. Avoid overly aggressive bottom-dwellers that may harass it, and be cautious mixing with other sand-sifting gobies in smaller tanks, as territorial disputes can occur. Because they can startle and jump, a tight-fitting lid is strongly recommended—particularly during the first few days while acclimating.
Reef compatibility is excellent, but keep in mind their sand-moving habits. They may dust nearby corals with sand if frags are placed low or too close to their “work zone,” so it’s best to mount sensitive corals higher up and keep the sandbed area clear around their preferred path. With a mature sandbed, secure aquascape, and regular feeding, the Sleeper Striped Goby is a hardy, helpful addition that keeps your substrate looking fresh and active.
